Definition
Metamorphic rocks are formed from the alteration of pre-existing rocks under extreme temperature and pressure conditions, resulting in significant changes in mineral composition and texture. They play a crucial role in understanding geological processes and the history of the Earth's crust.
Summary
Metamorphic rocks are a fascinating category of rocks that form through the transformation of existing rocks under heat and pressure. This process, known as metamorphism, can alter the mineral composition and structure of the original rock, resulting in unique textures and appearances. Understanding metamorphic rocks is crucial for geologists as they provide valuable insights into the Earth's geological history and the processes that shape our planet. These rocks are not only significant in geological studies but also have practical applications in various fields. For instance, they are widely used in construction and art due to their durability and aesthetic qualities. By studying metamorphic rocks, we can better understand the dynamic nature of Earth's crust and the forces that drive geological change.
